The present study is based on the field observations and geochemical analyses of flood sediments to ascertain nature causes destruction in Mandakini Alaknanda river valleys during June 2013.The suggests that were contributed from two major sources: moraines alluvial fans located Trans Higher Himalaya; landslides Lesser Himalaya.Although was result a high intensity rainfall event, magnitude increased due proliferation settlements along series partially constructed barrages bed.Geochemical...
ABSTRACT Detailed geomorphological investigation supported by field stratigraphy and optical dating enabled us to identify three major events of glaciation in the eastern Zanskar Himalaya (Sarchu Plain). The oldest most extensive is Sarchu Glaciation Stage‐1 (SGS‐1) that pre‐dates Last Glacial Maximum (LGM) assigned cold wet Marine Isotope Stage‐4 (MIS‐4). second glacial advance (SGS‐2) optically dated ∼20 ka youngest SGS‐3 8.2 cooling event. Evidence deglaciation preserved as outwash...
Abstract Geomorphic analysis and optically stimulated luminescence (OSL) ages from undated Lake Agassiz beaches adjacent fluvial sediments on Riding Mountain in Manitoba provide insight into their early history. New OSL of 14.5±2.4 13.4±0.7 ka the oldest (Herman to Norcross) near Canada-U.S. border indicate that Laurentide Ice Sheet (LIS) retreated part basin by ~14.5 ka. To north along Mountain, Herman strandlines are absent, beach there average 12.9 ka, which links it younger...
The legendary river Saraswati of Indian mythology has often been hypothesized to be an ancient perennial channel the seasonal Ghaggar that flowed through heartland Bronze Age Harappan civilization in north-western India. Despite discovery abundant settlements along a major paleo-channel Ghaggar, many believed Harappans depended solely on monsoonal rains, because no proof existed for river's uninterrupted flow during zenith civilization. Here, we present unequivocal evidence Ghaggar's past by...
